Abstract (en)
[origin: US2017307778A1] A silicone elastomer-hydrogel hybrid contact lens includes a silicone elastomer layer and a hydrogel layer adhered to the silicone elastomer layer by a delamination-resistant bond that is formed by an elastomer-swellable monomer that is included in the polymerizable composition used to form the hydrogel layer.
